Iron Man 3's production code name is an interesting one

The particular code name for something in production doesn't always mean much, or is often just utterly inscrutable to anyone except the person who came up with it. Microsoft's follow-up to the XBOX 360 bears the code name Durango, for example. That being said, according to investigation by the folks over at Comicbook.com, "Iron Man 3 is currently in pre-production under the code name “Caged Heat.” I would strongly doubt that this shows up on any poster though, as it would be a bit weird considering how neither of the first two movies had any sort of subtitle. "Even though Iron Man 3 has been officially announced as filming in Wilmington, the code name “Caged Heat” is still being used by various sources in the local Wilmington film industry."

And in another small confirmation of our previously reported start date for shooting: "Comicbook.com has reporters on-site in Wilmington, North Carolina where Iron Man 3 is scheduled to film at EUE/Screen Gems Studios. We’re hearing reports that set construction has already begun. As far as filming, we’re still hearing the target for initial filming will be very early May (with a possibility of late April)."

IRON MAN 3 is to be directed by Shane Black (KISS KISS BANG BANG) and will see the return of Robert Downey Jr., Gwyneth Paltrow, Don Cheadle, Jon Favreau, and (very) possibly Scarlett Johansson. Look for it May 3rd, 2013.

On a side note: Comicbook.com also has a very interesting (month-old) piece that speculates as to how Prince Namor/Sub-Mariner may in fact be the main villain of IRON MAN 3. You can read all about it right here.
